[PFS] Wayang Shadowcaster Wizard. Advice? Thoughts?

[Capricornus]

I am considering taking the plunge and using my chronicle sheet for a Wayang Shadowcaster Illusionist Wizard. I started out just working on the mechanics, but the concept has been percolating in my mind and he's starting to develop in an interesting, if odd way. Details in spoiler.

Choices:

For stats, I'm looking at S 8, D 14, Co 12, I 20, W 8, Ch 11. (The Cha is so I get access to the Wayang spell-like abilities, but I am considering upping it a bit.)

For Specialization: Illusion. Shadow spells are Illusion, and I can boost save DCs pretty high this way. The Illusion school abilities are decent for this.
Prohibited schools: Evocation and... Can't decide on this. Necromancy is the leading contender, but I like the idea of Necromancy spells for this character.

Archetype:Shadowcaster. Flavourful! Plus I love having lots of spells per day, and the Shadowcaster Shadow Casting is nice that way. I don't like having to waste the Darkvision the archetype gets at 5th level, since Wayangs get it anyway, but I'll have to deal with it.

Feats: Spell Focus: Illusion (Wizard Bonus - it's Pathfinder Society), Improved Initiative (1)

Traits: (here's where it gets a bit odd) Uskwood Hunter (Nidal Regional Trait, +1 Stealth and Stealth becomes a class skill. Take advantage of Wayang's small size and racial bonus to Stealth), and Adopted (By Goblins, to gain Ugly Swine, +2 to Disguise checks, Disguise becomes a Class Skill). When I was building the character I knew I wanted Stealth, and then left the second trait choice blank as I went on to select spells and other things. Then the image came to mind of a Wayang kidnapped and taken to Nidal as a child, who escapes and then is adopted by Goblins and raised in a community of various small Monstrous races hiding from the Umbral Court. They take in a Pathfinder who is hiding from the authorities and he helps them in return and exposes my character to the Society. He later runs away to join the Society. The Disguise reflects the paranoia and layers of defenses he sets up around himself. He often disguises himself as a Tengu, or a Gnome, afraid to be identified as a Wayang.

Skills: Some knowledges, a Craft skill (Puppets!), Disguise, Stealth, Spellcraft. I may grab a point in Perform: Puppetry. Because Flavour. And the Shadow Stencils item from the Advanced Race Guide.

Spells: Color Spray, Comprehend Languages, Disguise Self, Illusion of Calm, Mage Armor, Minor Image, Shield, Vanish

I wanted to try to fit in Shadow Weapon. Because Flavour. Not sure what to drop for it though or buy a scroll or wait until level 2 and pick it up.

Thoughts?

Your DC's are going to be amazing, but there are a limited selection of shadow spells. Tenebrous Spell is nice, but umbral/shadowgrasp probably aren't worth taking. Better off with spell focus, GSF and spell penetration, GSP.

You can (should) combine this with illusion specialization.

[Capricornus]

I am definitely going to specialize in Illusion. The shadow spells are a bonus.

[Tangaroa]

Ah sorry, missed that. Also, maybe spell specialization shadow conjuration/evocation? The caster bump coupled with the versatility would be nice.

I'm personally a fan of opposing divination. For identifying you can use up two cantrip slots (they are hardly useful after a few levels anyway), or you can pick up a wand of detect magic. You lose very few useful spells, and you get to keep false life, vampiric touch, spectral hand and other awesome tricks.

[Capricornus]

Ah, Spell Specialization looks interesting. Maybe not until 5th level though.

Opposing Divination? I hadn't thought of that. I was thinking I wasn't allowed for some reason... echoes of 3.5 maybe. Hmm. Losing Read Magic and Detect Magic is tough at low levels. Or maybe I'm over thinking that. Well, yes, maybe I'll try out opposing Evocation and Divination. Seems a little short-sighted for a paranoid from Nidal though.

Has anyone ever used Arcane Discoveries from Ultimate Magic? Too bad the Opposition Research one is 9th level or later.

I'm looking forward to getting Feral Speech for my conjurer. Being able to speak at will to any animal will be useful for getting advanced tactic from my summons (he's also learning elemental languages with Linguistics).

It's also just cool. It's something that only druids can typically do, and only if they prepare it. I am so going to have long conversations with a ranger's animal companion while the ranger yells out "What's he saying? What are you telling him?!"

Fast Study could also be useful depending on whether you tend to leave spell slots open.
